19) Les tablettes de Tărtăria (Tărtăria tablets)

The Tărtăria tablets are three tablets, discovered in 1961 by archaeologist Nicolae Vlassa at a Neolithic site in the village of Tărtăria (about 30 km from Alba Iulia), in Romania. The tablets, dated to around 5300 BC, bear incised symbols - the Vinča symbols - and have been the subject of considerable controversy among archaeologists, some of whom claim that the symbols represent the earliest known form of writing in the world.
